The Sacramento Kings agreed in principle to a deal with the Boston Celtics on Monday night, a league source told ESPN.com. The Celtics will send Sam Cassell and cash to the Kings for a future second-round pick.

Barring any changes overnight, the deal is expected to be finalized Tuesday afternoon with the league office.

The deal helps the Celtics by removing Cassell's salary from the team's luxury-tax computations. The Kings give up virtually nothing to do it as the pick is heavily protected. Furthermore, another league source says the deal could pave the way for the Celtics to add another player to their roster prior to the playoffs. The Celtics had a maximum of 15 players on their current roster.

While it's unclear what the Kings will do with Cassell, most likely they'll waive him.

I guess it's like our trade? Colangelo today said, him trading a pick wouldn't have happened unless he got money in return which allows him to recoupe a draft pick if we make the plaoffs next season. Essentially, kinda like swaping draft picks.
